# Ansible Install
This repo provides a simple way to set up OpenSSH and configure public keys on multiple Ubuntu machines to prepare them for Ansible automation.
## Features
✅ Installs OpenSSH on target Ubuntu machines.
✅ Adds your public SSH keys for seamless Ansible access.
✅ Includes a sample `hosts.txt` file for Ansible inventory.
---
## Step 1: Clone the Repository
To get started, clone this repository to your local machine:
```bash
git clone https://github.com/michaelbolanos/ansible-install.git
cd ansible-install/scripts
```
---
## Step 2: Configure Your Hosts File
Edit the `hosts.txt` file to include the IP addresses or hostnames of the machines you want to manage with Ansible:
```plaintext
192.168.1.100
192.168.1.101
192.168.1.102
```
---
## Step 3: Install OpenSSH via Curl or Wget
Run the following command on each Ubuntu machine to install OpenSSH.
### Using `curl`
```bash
curl -sSL https://raw.githubusercontent.com/michaelbolanos/ansible-install/main/scripts/install_ssh.sh | bash
```
### Using `wget`
```bash
wget -qO- https://raw.githubusercontent.com/michaelbolanos/ansible-install/main/scripts/install_ssh.sh | bash
```
---
## Step 4: Copy SSH Keys to Remote Machines
To enable passwordless SSH authentication, use the provided `ssh-keys.sh` script. Run this from your control machine:
```bash
bash ssh-keys.sh
```
This script will:
```bash
# Copy SSH public key to each host in hosts.txt
while read -r host; do
ssh-copy-id -i ~/.ssh/id_rsa.pub "ubuntu@$host"
done < hosts.txt
```
- Copies your SSH public key to each host listed in `hosts.txt`
- Ensures secure key-based authentication
---
## Step 5: Verify SSH Access
Once keys are copied, test SSH access to the remote machines:
```bash
ssh ubuntu@192.168.1.100
```
If login works without a password prompt, you're ready to use Ansible! 🎉
---
## Next Steps: Set Up Ansible
Now that SSH is configured, install Ansible and begin automating your infrastructure.
```bash
sudo apt update && sudo apt install -y ansible
```
You can now create an Ansible inventory file and start managing your machines
